Garmin Fenix 5 elevation way off

I have had issues with the elevation readings all summer long. I consistently am missing at least 50%(and usually more) of my total elevation gain while cycling or mountain biking. I usually end up enabling the Elevation Correction. I have been in contact with support. On the first call, they told me to upgrade to the beta software and clean the sensor. I did both, and it still read erroneously. On the next call, I was instructed to default it back to factory settings and try again. After doing this, repairing all my sensors, etc, the elevation gain was still off by at least 50%. On the next call, they agreed to replace it under warranty. I recieved the new device, set it up, and it is doing the EXACT SAME THING. I now believe there is a software bug with 9.20. Does anyone else experience this? I can't believe I am the only one who has this issue, on 2 completely separate devices. Anyone from Garmin Support on here that can address this? This is a 600 dollar device and I believe it should work correctly. I hate having to use the USGS tables for elevation as they are highly inaccurate when mountain biking.
